I first heard about the JPLAY app on a posting in this forum a couple months ago.
It's recently been released for iOS by the JCAT group.
Because of my equipment I had only been able to use M-Connect to stream to my Ifi Zen Stream. I was using Tidal Connect with the Ifi Zen but I've since cancelled my Tidal account.
Qobuz has sounded terrific via the M-Connect app into my Zen Stream but the app itself is uninspired to say the least.
I've been using JPLAY for the past month or so and, while there's been a few bugs, the developers are releasing rapid fire updates to accommodate issues that come up.
I love how you can have both your Tidal and Qobuz account on the JPLAY app and the search function allows you to select which record from which service and which version to play. Also the metadata and any liner notes available are more more accessible with JPLAY. Lastly, it's a beautiful looking app.
The cost for the app is about $54.
I hope they somehow figure out a way to include Idagio at some point.
